EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 731,081, dated June 16, 1903.

Application filed June 9, 1902. Serial No. 110,797. (No model.)

My invention relates to improvements in eyeglasses.

The object of my invention is to provide a post-lock for eyeglasses that will securely and permanently hold the nose-guard and spring in position on the post. f

My invention relates to the kind of eyeglasses in,which the post is provided at one end with flanges adapted to receive between them the end of the spring.

My invention provides a plate disposed between the flanges of the post and provided at each side with a lateral arm extending beyond the flange, said lateral arm embracing the outside of the adjacent flange.

My invention provides, further, a post having flanges each provided with a transverse slot, the end of the spring being adapted to lie between the flanges, and a securing-plate disposed between the flanges and having arms extending through the slots beyond the flanges, the outer ends of said arms extending laterally and embracing the ontsides of the flanges.

In practicing my invention the securingplate may be a separate member or it may be a portion of the arm connected with the noseguard.

In the accompanying drawings, which illustrate myinvention, Figure 1 represents a perspective view of the form of my invention in which the securing-plate is also the" arm of the nose-guard. In this view a portion only of one lens and one end of the spring is shown. Fig. 2 is a perspective view of the post provided with the slotted flanges. Fig. 3 is a central vertical sectional view of the device shown in Fig. 1. Fig. 4 is an end View of the post, showing also the nose-guard and part of the spring. Fig. 5 represents a plan and edge view of a modified form of my securing plate.

Fig. 6 represents in plan the secu ring-plate.

and side elevation another modification of Fig. 7 represents an end view of the post, part of the nose-guard arm,

and part of the springin position between the flanges of the post. Fig. Sis aview similar to Fig. 7,-the separate securing-plate being shown in position on the post. Fig. 9 is a plan and side elevation of still another modification of the securing-plate. Fig. 10 is a side elevation view of the parts shown in Fig. 8.

Similar n u merals of reference indicate similar parts.

1 indicates the post, provided at one end with the two ears 2, between which the lens 3 is secured. The other end of the post is provided with two parallel flanges or projections 4, each of which is provided with a transverse slot 5. One end of the spring 6 is adapted to rest between the said two flanges and is held in position by means of a securing-plate, which is disposed between the said flanges outside the spring and which extends laterally beyond the said flanges and embraces the outside thereof for the purpose of preventing the flanges from, spreading laterally.

Referring to the first four figures, the securing-plate comprises the arm 7 of the noseguard 8. The arm 7 is disposed between the flanges 4 and is provided with an opening through which extends the securing-screw 9, which passes throughthe spring 6 and engages at its inner end a screw-threaded hole located in the end'of the post 1, between the flanges. At each side of the arm 7 is provided a lateral arm 10. The two arms 10 lie in the slots 5 of the flanges. At each side of each of said lateral arms 10 is a projection 11. The projections lllie against and tightly embrace the outsides of the flanges 4. By this construction the flanges 4 are prevented from spreading due to strain applied laterally to the spring 6 or the nose-guard 8.

In the form of my invention illustrated in Fig. 5 the arm 7 is provided with four holes 12, which fit over the projections at the ends of the flanges 4.

In the form shown in Fig. 9 two slots 12 are provided, which extend the full length of the this construction the slot 5 may be dispensed with.

In the forms shown in Figs. 6, 7, 8, and 10 the securing-plate is a separate member, which is indicated by 13. The secu ring-plate 13 lies between the flanges 4: and is provided in the same manner as the arm 7, in the forms already described, with the lateral arms 10, which fit tightly in the slots 5, and are provided at their outer ends with the lateral projections 11, which lie against and tightly embrace the outsides of the flanges 4.

In the form of my invention shown in Figs. 6, 7, 8, and 10' the lateral arms 10 on the arm 7 may be dispensed with, if desired.

It will be noted that with the constructions illustrated in the diti'erent views the flanges 4 are prevented from spreading outwardly by means of the securing-plate, which tightly embraces them on their outer sides. If it is desired at any time to remove the nose-guard or the spring, the securing-screw 9 may be moved from the post, after which the plate 13 can-be taken out and the substitution of a new spring or nose-guard made.

My invention may be variously'modified without departing from its spirit.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. In eyeglasses, the combination with the post provided at its end with two flanges disposed parallel with the axis of the post and adapted to receive between themthe end of the spring, of a securing-plate disposed between the said flanges and provided with openings through which the said flanges extend, said securing-plate being provided with lateral extensions embracing the outsides of the said flanges, substantially as described.

, 2. 1n eyeglasses, the combination with the post provided with two flanges disposed parallel with the axis of the post and adapted to receive between them the end of the spring, said flanges being provided each witha transverse slot, of a securing-plate disposed be tween the said flanges and having lateral arms disposed in the said slots and extending beyond and embracing the outsides of the said flanges, substantially as described.

3. In eyeglasses, the combination with the post provided at one end with two flanges adapted to receive between them the end of the springand provided each with a transverse slot, of the nose-guard. provided with an arm disposed between the said flanges and having lateral arms disposed in the said slots and extending beyond and embracing the outside of the said flanges, substantially as described. Y

4:. In eyeglasses, the combination with the post provided at its end withtwo flanges, and a screw-threaded hole, each flange being provided with a transverse slot, the flanges being adapted to held between them the end of the spring, of the nose-guard provided with an arm disposed between the said flanges, said arm being provided with lateral arms disposed in the said slots, each 0t said lateral arms being provided at its outer end with projections embracing the outside of the adjacent flange, and a securing-screw extending through the arm of the nose-guard and engaging the post in the said screw-threaded hole, substantially as described.

5. In eyeglasses, the combination with a post provided with a plurality of projections extending from one end thereof parallel with the axis of the post and parallel with each.

other, of asecuring-plate located between the said projections and provided with lateral projections which extend between the projeotions respectively, each of said projections'on the plate being provided outside the projections on the post with two oppositelydisposed projections extending at right angles to the projection on the plate of which they form a part, substantially as described. In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
